SUSPENSION-LAMP.

SPECIFICATION forming part of Letters Patent No. 657,486, datedSeptember 4, 1900.

Application filed March 23,1900. Serial No. 9,918. (No model.)

To all whom it may concern:

Be it known that I, WALTHER FHNDRICH, manufacturer, a subject of theEmperor of Germany, residing at Neustrasse, Hamburg,

in the Empire of Germany, have invented certain new and usefulImprovements in Suspension-Lamps, of which the following is aspecification.

This invention relates principally to sus- ;o pension gasdamps, and hasfor one of its objects to arrange the metallic suspension fittings withthe gas-supply pipes in such a manner that they are removed from theiniuence of the products of combustion arising from 'the burner of suchlamps, so that such fittings whenmade of polished brass or the like arenot liable to be tarnished or discolored by the ascending heat andfumes, as now commonly occurs in suspension-lamps. An-

2o other object is to facilitate the removal and replacement of theglobe or shade, while a third object is to so arrange the suspensionarms or pipes that they are disposed inside the globe, by which a noveland elegant ap- 2 5 pearance is impartedto the lamp.

Figure l of the accompanying drawings represents a side elevation of asuspension gas-lamp constructed and arranged in accordance with myinvention, but with the globe 3o or shade and its detachable supportshown in section. Fig. 2 is a front elevation of the said lamp with thesame parts in section. Fig. 3 is a front elevation of the lamp, showinghow the globe or shade is introduced into position from below and alsoshowing the detachable support of the lamp in section and separately.Fig. al represents a View of a. lamp in which only a singlesuspension-arm is employed. Fig. 5 is a View, partly in side 4oelevation and partly in section, showing a stop-cock fitting inlongitudinal section.

The same letters of reference indicate corresponding parts in theseveral figures of the drawings. Y

In the construction represented in Figs. 1, ,n :2, and 3, VoL-is aterminal fitting in connection with a gas-supply, being either asuitable wall patras or a part of a chandelier, and has proceeding fromit a branched or bifurcated 5o bracket b, from the separatedterminations b l of which a hanger consisting of a pair ofsuspension-arms c depends and is connected at its lower end c' to thecasing or body part d of a stop-cock, into which a plug CZ/ is iittedfor controlling the supply of gas to a superimposed burner e, carrying agallery f, upon which thechimney g rests. This chimney is disposed inthe middle of the lamp and between the branched or spreading members ofthe bracket b, which are so disposed relative 6o to the eXit to thechimney that the products of combustion arising from the latter aredelivered clear of the said suspension members. Either'one or both ofthe branches and suspension-arms constitutes a gasway for supplying theburner wit-h gas.

Surrounding and inclosing both the burner with its chimney and thesuspension-arms is a globe or shade h, carried by a separable supportz', having a seat for the globe and de- 70 tachably connected to awol-med neck d2 of the stop-cock casing d by means of a screwed collart", forming a part of the said support, which said collar is ofsuiiicient diameter internally as to clear and admit of passing over theturn d3 of the stop-cock plug d. It will thus be seen that thesuspension-arms c are disposed between the chimney and the globe, whichlatter, with its support, is introduced into position around the armsand So chimney7 from below when the support is removed (see Fig. 3) andis retained or held in its proper position, as shown in Figs. l and 2,by screwing the support, as aforesaid, onto the neck of the stop-cockcasing.

It is obvious that instead of supporting the burner, chimney, and globeof the lamp by bracket branches and suspension-arms arranged induplicate, as in Figs. l to 3, the. said parts may equally be supportedby a 9o single bracket member Z9 and suspension-arm c, as represented inFig. 4, with the said arm c still coming between the outer shade handchimney g, or the single suspension-arm may proceed direct from asuitable terminal in- 95 stead of depending from a branch or bracket, asshown.

In the drawings I have shown the preferred manner of detachablyconnecting the support to the lamp, but except in so far as specificlooally mentioned in .the following clauses'of claim my invention is notconfined to that preferred form.A

While lIv have shown speciically herein a particular form of stop-cocktting, it is to be understood that I do not limit my invenvlfion orclaims to that particular form; -bntit is merely illustrative of one:suitable-arrangementof stop-cock fitting.

Having fully described my invention, what I desire to claim and secureby Letters Patent i'sl. In suspension 1amps, the combination with adouble-armed or branched bracket, of a hanger consisting of a pair ofdepending` arms arranged to come-between the globe and the chimney ofthe lamp,.and terminatingin a burner-fitting, to which a support vforthe said globe is detachably secured to ,admit of 'g the globe beingintroduced into position from below, substantially as and for the.purpose described and also as set forth panying drawings. c

3. In suspension-lamps, the. combination with a bracket or support, of ahanger coming between the globe and chimney ofthe lamp and terminatingvin a burner-fitting, to -which a-globe-support -is detachably securedin the accom# atoadmit of thesaid globe being introduced into positionfrom below, substantially as herein described, and also as set forth inthe raccompanying drawings.

4. Ina suspension-lamp, the combination with av double-armed or branchedbracket, a

'hanger consisting of Va pair of depending arms arranged te go betweenthe globe and the chimney of the lamp, a burner-fitting supported bysaid :hanger and provided with ja screwed neck, va chimney arranged overthe burner-.fitting a'support having a detachable screw connection withthe screwed `neck of the burner-.fitting and :provided with a seat forthe globe,.and a globe resting in said seat,

L' allso arranged that the .globe maybe introduced into position frombelow, substantially as described. y

In testimony whereof I have hereunto set my hand Yin presence of twosubscribing witnesses.
